How to build 6.1.0

The Readme still states:



```

sudo apt install build-essential libgflags-dev libprotobuf-dev protobuf-compiler libsodium-dev cmake git

git clone --recurse-submodules https://github.com/MisterTea/EternalTerminal.git

cd EternalTerminal

mkdir build

cd build

cmake ../

make && sudo make install

sudo cp ../etc/et.cfg /etc/

```



However I get:

```
